IMPROVEMENTh IN CVLINDERS FOR LINING WOODEN PUMPS.

Specification forming part of Letters Patent N0. 140,@02, dated July 15,1873; application led Y April 2o, 1873.

To all whom it may concern:

Be it known that I, RICHMOND W. WHEEL- ER, of Bushnell, in the county ofMcDonough and State of Illinois, have invented a new and usefulImprovement in Cylinders for Lining Wooden Pumps; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the ac companying drawing and to theletters of reference marked thereon making a part of this specification,in whichy Figure 1 is a perspective view of the cylinder. Fig. 2 isalongitudinal section, showing the cylinder inserted in the wooden pump.

My invention relates to that class of cylinders for lining woodenpumps-that is, made of cast-iron and lined on the inside with porcelain.My invention consists in amore substantial means of securing thecylinder rigidly to the pump-stock. g

This I do by having cast on the cylinder a Wedge-shaped ring, shown ata, Figs. l and 2, the cylinder being driven into the pump-stock untilthe ring a is some two or three inches beyond the end of the pump-stock,as shown in Fig. 2, at a; then an iron band, shown at c, is driven overthe end of the wooden stock,

fwhich shrinks the wood down over` the edge
